GU rear door

hello all,

i have an 03 Gu patrol and there is a rattle / vibrate noise in the rear door, it is killing me. i have checked everything and it is still there.

I have taken it to my nissan dealer a number of times and all they do is grease the seals, they are useless.

i have a 35 inch spare on the rear door,

When i take the spare off it goes away, i have been told that a 35 is to much weight for the rear doors. is this true?

has anyone else had problems with there rear doors?

I have been told to put a rear wheel carrier on for the spare, i am not a fan of the look of them.
